Title: Improvements in or relating to thermal evaporation of metals in a vacuum
IPC: C23C14/02
Filed: 1944-11-30
Abstract: 599,694. Coating by vapourised material. ALEXANDER, P. Nov. 30, 1944, No. 32932. [Class 93] [Also in Group II] In a process of forming a coating on the surface of a support, the surface, having a layer of adsorbed water vapour, is exposed to the vapour of a metal having, in the vapour state, a strong affinity for oxygen and impact of the vapour is stopped before a deposit of metal is formed by separating the exposed surface of the support from the area of high-pressure liberated hydrogen whereby a thin coating of metal oxide is formed on the surface. As shown, a web of paper is drawn by feed rolls 8 from a storage roll 4a over an idler roll 7 where it is subjected to the impact of a metal vapour from a vapouriser 11 and wound on a receiver 5a, the whole apparatus being enclosed in a vacuum chamber 3. The rate of travel of the web, the rate of evaporation of the metal and the position of a screen 13 are so adjusted that the web is removed from the area of high-pressure liberated hydrogen gas as soon as the reaction of metal and water vapour is complete and before any metal is deposited, thus giving a layer of metallic oxide on the web. A thicker layer of oxide may be obtained by directing water vapour on the web from a tube 14. Fig. 4 (not shown) illustrates apparatus wherein a layer of metal may be deposited on the oxide film. A stationary support may be coated by the use of screens 19 pivoted at 20, 21 which cut off the vapour when the oxide coating is complete. Specifications 485,965, 551,220, [both in Group II], and 593,468 are referred to.

Title: Urea synthesis using excess ammonia
Inventor: OTSUKA EIJI
IPC: C07C273/04
Filed: 1958-07-25
Abstract: A process for the production of urea by the reaction of 4-5 moles of ammonia with 1 mole of carbon dioxide at 180 DEG C. and 280 atmospheres pressure includes the steps of subjecting the urea melt from the synthesis zone to distillation at 90 DEG C.-120 DEG C. and 10-15 atmospheres pressure to separate a mixture containing a major proportion of unreacted ammonia and a minor proportion of unreacted carbon dioxide; scrubbing the mixture with a limited quantity of water to remove substantially all the CO2 contained therein, thus producing pure ammonia which is liquified for delivery under pressure to the synthesis zone, and an aqueous ammonium carbonate solution; subjecting the treated urea melt to a further distillation at 1-3 atmospheres pressure to remove substantially all the remaining NH3 and CO2 together with a substantial proportion of the water produced in the synthesis: dehumidifying the latter mixture to produce a gaseous product containing 7%-10% water; absorbing said gaseous product in said aqueous ammonium carbonate solution at 80 DEG C.-140 DEG C. and 20-50 atmospheres pressure; and recycling to the synthesis zone the NH3- and CO2-containing product so obtained, having a water content of 10%-15%.  An intermediate distillation of the urea melt may be carried out after the first distillation at 10-15 atmospheres, said second distillation being at 20-50 atmospheres to separate a mixture of unreacted NH3 and CO2 which is absorbed directly in the aqueous ammonium carbonate solution.  A process for the dehumidification step by a rectification procedure is described.

Abstract: 965,532. Roll film. KODAK Ltd. Aug. 11, 1960 [Aug. 19, 1959], No. 24715/63. Divided out of 965, 531. Heading G2A. A roll film strip has a plurality of perforations spaced along its length so as to co-operate with metering mechanism within a camera, and a plurality of light sensitive areas spaced in succession along the strip, each of said areas having the same definite spatial relation to a corresponding perforation. Fig. 2 shows the film strip from the side opposite the emulsion side, with an adhesive strip 14 for attaching the leading edge 16 to a backing paper strip (not shown). On the emulsion side are formed a series of uniform sensitive exposure areas 17 equi-spaced along the film strip, and a series of metering perforations 18, each perforation occupying the same position relative to a corresponding area 17. The areas 17 are defined by previously exposing, during manufacture, the emulsion surface surrounding them, except for end areas 31 and a marginal area 32, utilized for film identification. It is intended that the exposure area 17 shall be appreciably smaller than the camera aperture, so that all of the area 17 is exposed even if it is not exactly centred in said aperture. Similarly the aperture of the printer or enlarger is to be larger than the area 17. Thus the final print will always correspond exactly to the negative.

Title: Method of producing crimped viscose fibres
IPC: D01D5/22
Filed: 1957-08-06
Abstract: Crimped regenerated cellulose fibre is made from viscose by submitting freshly spun filaments emerging from a conventional spinning bath to a stretch equal approximately to one third of the total stretch to be imparted, while the filaments still substantially consist of cellulose xanthate and while they are still in the plastic state, conducting the partly stretched filaments through an acid bath for their further though not yet complete transformation into cellulose hydrate, subjecting them either in, or outside, this bath to a second stretching which corresponds to the difference between the initial stretch and the total stretch, and then, after substantially completely transforming the filaments into staple lengths, immersing the staple lenths in a hot water or alkaline bath, and finally submitting them to conventional after-treatment. Preferably the partially stretched filaments are 70-95% converted to cellulose hydrate prior to the second stretch, which may be carried out in an aqueous sulphuric acid bath.  Preferably, also, the viscose has a ratio of alkali to a -cellulose of below 0.9, e.g. 0.8-0.85. The total stretch of the fibre may correspond to 60-65% of its original length.  An example is given.  Specification 499,671 is referred to.

A sliding headstock automatic lathe working on bar stock is adapted to transfer partlyformed workpieces to a milling station for cutting teeth on the work by a form cutter. The arrangement is similar to that of Specification 907,167 but instead of the teeth being cut by a generating action each tooth is cut individually by a form cutter and the work indexed and the tool relieved during cuts. The workpiece 2, after parting, is transferred by the arm 5 to the chuck 75 and centre 10 of the auxiliary headstock and tailstock 6a, 9, respectively by mechanism similar to that of the above Specification. The milling cutter 8a is carried by a horizontal slide 66 and a vertical relieving slide (not shown). The feed movements &c. of the slides and the indexing of the workpiece is controlled by a cam-shaft 67. This cam-shaft is driven by gears 102, 106 from a cross-shaft 85 through an electromagnetic clutch which is automatically operated to stop the cam-shaft while the workpieces are being transferred. A further hand-operated clutch 91, 97, on shaft 85, is provided to stop the drive to a gear 96 which drives the other two cam-shafts required by the automatic lathe. The first of these, 4, controls the normal tool feed and sliding headstock operation of the main parts of the machine while the second, 11a, controls the work-transfer operations. A switch mechanism on the end of the latter controls the electromagnetic clutch for cam-shaft 67. By varying gears 98-100 and gears 102, 106 different numbers of teeth may be cut on the workpieces.

Abstract: 599,532. Driving mechanism for toys. MALET, C. J. E. (Doyle, F.). Sept. 26, 1945, No. 24976 [Class 132 (iii)] Driving mechanism for toys and the like comprises a length of elastic cord anchored at one end to a power axle or a shaft mounted rotatably on a fixed part of the toy such as the chassis, and extending from the power shaft in zig-zag formation round a plurality of guides or idler rollers spaced laterally apart to a point on the fixed part to which it is attached. The chassis A of a toy car carries a body A<1>, axles B and C and road wheels B<1> and C<1>. The rear axle C has a central power disc C<2> secured to it through an aperture in which is passed the loop of a single length of elastic cord (of which only one length D<1> is shown) both ends of the loop passing round a grooved idler roller E at the front of the car, back again round another idler roller E' at the back and thence through a spacer E' to be anchored at D. The power disc C<2> is locked by the action of a disc F mounted eccentrically on a shaft. Both discs C<2> and F have soft rubber treads which are normally maintained in contact by the weight of a control trigger F<4> which is fixed to the disc F. The lower curved end of the trigger co-operates with the floor surface. A handle G is provided to wind the elastic cord on the power axle. The toy is lifted from the floor and the handle turned in that direction which will not cause the power disc and locking disc to jam until the requisite tension has been applied throughout the length of the cord. On releasing the handle G the disc C<2> will move slightly in the opposite direction until the disc F jams against it. On placing the toy on the floor the trigger F<4> is pushed up slightly but not enough to break the contact between the discs. A slight pressure on A<1> will cause the trigger to move the disc F sufficiently to break contact and the toy will travel freely until it is picked up off the floor, whereupon the weight of the trigger F' will turn the disc F back until the two discs jam together again. Other forms of trigger release may be provided, and the number of idler rollers be increased. Specifications 123,464 and 145,822 [both in Class 132 (iii)], are referred to. Reference has been directed by the Comptroller to Specification 589,143.

Abstract: 784,264. Agglutinated fibrous sheet materials. CELANESE CORPORATION OF AMERICA. Aug. 31, 1955 [Sept. 3, 1954], No. 24990/55. Class 140. A batting of staple fibres is treated to bond the fibres together to form a coherent product in which the degree of bonding decreases from each surface towards the interior. The process comprises applying to one surface of the batting a volatile solvent for the fibres, applying suction to the other surface to draw solvent vapours through the body of the batting, and subsequently applying the solvent to the said other surface and suction to the first-mentioned surface. The operations are effected while the batting is uncompressed. The solvent causes the fibres to coalesce or bond one to the other at their points of contact. Specified materials of which the fibres may be made are polyhexamethylene adipamide, polyamino-caproic acid, polyethylene terephthalate, polyurethanes, polyaminotriazoles, polymers and copolymers of vinyl chloride, cellulose acetate, propionate, butyrate, acetate-formate, acetate-propionate, acetate-butyrate, cellulose benzoate, and ethyl cellulose. The fibres may be crimped before being incorporated into the batting materials. The batting may be formed by carding or airlaying. Specified solvents for the fibres are acetone and chlorinated hydrocarbons, either alone or in admixture with lower aliphatic alcohols. As shown, a batting of fibres 11 is carried on an endless foraminous belt 12 under nozzle 15 from which a spray of solvent issues, and over a suction-box 16. The belt then carries the batting over suction-box 18 whereby the major portion of solvent remaining in the batting is removed. The batting then drops one to a plate 21 which directs it on to an endless foraminous belt 22 with the previously untreated surface of the batting uppermost. Belt 22 carries the batting under a solvent-spraying nozzle 25 and over a suction-box 26. The belt then carries the batting between a heater 28 and a suction-box 29 whereby all the residual solvent and solvent vapours are removed from the batting, which is taken up in the form of a roll 32.
